T1 Pelvic and Lumbar Pelvic Angles Normative Values: A Prospective Cohort Study of 472 Asymptomatic Volunteers.

Study Design: Cross-sectional analysis of a prospectively enrolled cohort.

Objective: Determine the normative values of the T1 Pelvic Angle (TPA) and Lumbar Pelvic Angle (LPA) in an asymptomatic cohort of volunteers.

Summary Of Background Data: The TPA and LPA have been introduced as sagittal spino-pelvic parameters to guide correction of adult spinal deformity.

Retroarticular drilling for osteochondritis dissecans of the talus: A systematic review.

Background: Opinions differ on the optimal treatment for stable talar osteochondritis dissecans (OCD) with intact cartilage. Some recommend conservative management, while others prefer surgical care, which includes debridement and micro-fractures, transarticular drilling through a direct or medial malleolus approach and retroarticular drilling. The rationale behind retroarticular drilling is to induce bone marrow healing without touching the intact cartilage.

Validation of a New Tool to Detect and Characterize Spinal Cord Injury in the Acute Trauma Patient: The Montreal Acute Classification of Spinal Cord Injury.

Study Design: Retrospective validation protocol.

Objective: The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most comprehensive tool for classifying spinal cord injuries (SCI), but it is not adapted for the evaluation of trauma patients. The objective is to develop and validate a streamlined tool, the Montreal Acute Classification of Spinal Cord Injury (MAC-SCI) that can be integrated in the evaluation of trauma patients to detect and characterize traumatic SCI (tSCI).

Subchondroplasty in the treatment of bone Marrow lesion in early Knee Osteoarthritis: A systematic review of clinical and radiological outcomes.

Background: Knee osteoarthritis (KOA) is increasingly prevalent in North American society. The significant societal burden it represents makes it essential to promote and target new treatments in earlier phases of the disease. Among others, subchondroplasty is a newly documented technique using calcium phosphate injection targeting the osteochondral lesions preceding KOA, also known as Bone Marrow Lesions (BMLs).

Clinical judgment is a cornerstone for validating and using clinical prediction rules: a head-to-head study on ambulation outcomes for spinal cord injured patients.

Study Design: Retrospective comparative study.

Objective: Clinical prediction rules (CPRs) are an effervescent topic in the medical literature. Recovering ambulation after a traumatic spinal cord injury (tSCI) is a priority for patients and multiple CPRs have been proposed for predicting ambulation outcomes.

Electromyographic and kinematic study of reverse total shoulder arthroplasty: an observational prospective cohort study.

Background: Reverse total shoulder arthroplasty (RTSA) procedures have significantly increased in the last decade as an alternative to the current treatments for cuff-tear arthropathy. Since Grammont's theory in 1987, few data about the in vivo kinetics of the shoulder-girdle musculature in patients with RTSA have been available. The goals of this study are to (1) describe the contribution of principal muscles around the shoulder by electromyography and (2) access the range of motion of 5 movements of patients with RTSA compared with normal shoulders.

Traffic in the operating room during joint replacement is a multidisciplinary problem.

Background: Door openings disrupt the laminar air flow and increase the bacterial count in the operating room (OR). We aimed to define the incidence of door openings in the OR during primary total joint arthroplasty (TJA) surgeries and determine whether measures were needed and/or possible to reduce OR staff traffic.

Methods: We recorded the number of door openings during 100 primary elective TJA surgeries; the OR personnel were unaware of the observer's intention.

The Effect of Porous Tantalum Cones on Mechanical Alignment and Canal-Fill Ratio in Revision Total Knee Arthroplasty Performed with Uncemented Stems.

In revision total knee arthroplasty (TKA), the internal diameter of metal cones may limit the ability of the stem to properly fill the medullary canal. We prospectively studied 115 patients who underwent revision TKA with uncemented stems to evaluate the effect of metal cones on mechanical alignment and stem positioning. Correction on the mechanical alignment was well achieved in all patients, regardless of whether a metal cone was used.
